Primary Examiner-Elbert L. Roberts Attorney, Agent, or Firm-Benjamin F. Lambert 11 Claims, N0 Drawings O-(NITROARYL) ()XIMES OF 3-KETO STEROIDS where Z is a carbon to carbon single bond or a carbon to carbon double bond;

R and R are H or N0 and at least one of R and R is N0 R is H or CH,;

R is H or CH or CH CH or ethinyl;

R is H or CH R is hydroxy or the esters thereof, keto, or acetyl;

R is hydrogen or halogen, and R is H or halogen The compounds of this class which are potent antilittering are those where:

R and R are H or N0 at least one of R and R being N0 and when Z is a carbon to carbon single bond R is N0 and R, is H;

R is H or CH and where R, is H, R is CH R is H or CH or CH CH and where R is H, R

is also H;

R, is H or CH;,;

R is hydroxy or the esters thereof, keto;

R is hydrogen or halogen; and R is H or halogen.

The precursor ketones of these antilittering agents are generally ineffective as such and the parent oximes substantially less effective or ineffective.

The compounds are prepared from the parent keto steroids with the properly substituted O-arylhydroxylamine in the presence of an acid catalyst, or alternatively by reacting the oxime of the parent keto steroid with a properly substituted aryl halide in the presence of a suitable base, such as sodium hydride. The parent ketones are well-known in the art as are the methods of their preparation.

When it is desired to prepare a compound such as 3- (p-nitrophenoxy)imino-Sa-androstane-17-one wherein the A ring is saturated, it is ineffective to react the starting 3,17 dione with the O-aryl hydroxylamine since there may be substitution in both the 3 and 17 positions. In such a case it is necessary to first prepare a compound such as 3-(p-nitrophenoxy) imino-S a-androstan-17Bo1 by one of the above procedures and thereafter to oxidize the 17/3-01 substituent to the corresponding 17-one, preferably with the use of Jones so lution.

Various compounds of this invention are prepared as follows:

As noted previously many' compounds of this invention are potent antilittering agents. Antili'ttering activity ismeasuredas follows:

g A test group of rats is fed a calculated amount of a "test substance inthe'feed fora period of 7 days during which time males and females are kept separate withboth sexes receiving the test substance. Thereafter, the-males'a'ndfemales are cohabited and the 40 dietfed' is continued for 15 days. At the end of this group of rats is handled in precisely the same way at the same time except that their diet does not include thete'st substance. The following table illustrates the percentage of rats which give birth atthe dosage level indicated.

These compounds also exhibit postcoital antilittering properties when administered on days 9-12 after coitus' to the rat. The following table illustrates the percentage of resorptions obtained at the indicated dosage levels. The activity of the parent ketone and unsubstituted oxime is also noted.

tered days 1-12) While all of the compounds are at least weak anabolic agents, a number of the compounds are unusually potent anabolic agents. The compound of Example 11 has a ventral prostate potency of 0.15 as, compared to methyltestosterone and a levator ani potency of 2.1 when compared to methyltestosterone. Thus the anabolic:androgenic ratio is very favorable. This is also true of the compound of Example VI which has an anaboliczandrogenic ratio of 12.5 with a ventral prostate potency of 0.18 and a levator ani potency of 2.24 when compared to methyl testosterone, and the compound of Example X which has a ventral prostate potency of 1.9 and a levator ani potency of 4.6. XXXIII. The compound of Example XXXI is a highly antiandrogenic material as is evidenced by the following experiment.

Immature male rats, Wistar strain, 50 gm, were castrated under ether anesthesia. Two groups of 5 rats each were used, one as a control receiving only methyl testosterone, and the other as a treated group receiving methyl testosterone and drug.

The test material was administered per os in 0.2 ml sesame oil. Each dose (about 6.5 mg/rat/day) was administered daily for 7 days commencing on the day of castration. A total dose of 2.0 mg of methyl testosterone (MET) was administered concomitantly each day (about 0.3 mg/rat/day).

The animals were sacrificed (chloroform) 24 hours after the last drug administration. The ventral prostates were removed, cleaned of surrounding fat and connective tissue, incised and pressed on damp, No. 1 Whatman filter paper to express any contained fluid and weighed to the nearest 0.1 mg on a Mettler analytical balance. The percentage weight gain of the treated rats was substantially the same as that of the controls. The weight of the prostate of each treated animal which also received methyl testosterone was significantly reduced compared to the weight of the prostate from the rats receiving methyl testosterone alone. These weights 40 are shown in the table below:

Ventral Prostate From the above it can be seen that the weight of the prostates from treated animals who also received methyl testosterone was significantly reduced (22.8 percent reduction) over those from rats not treated.
